Description
BACKGROUND
Technical Field
[0001] The technology relates to the field of cleaning
formulations, applicators for such formulations, and methods of
using such formulations and applicators; more particularly, the
technology relates to removal of contaminated residues from
surfaces and sanitizing the surfaces.
Description of the Related Art
[0002] Cosmetics commonly referred to in the US as "make-up," have
been in use at least since the time of the Pharaohs. In the late
20.sup.th century, the use of make-up increased significantly with
the rise of major manufacturers and marketers such as Revlon,
L'Oreal, Estee Lauder, Elizabeth Arden, and many others. The term
"cosmetics" covers a wide range of products that are perceived to
enhance beauty. Often, cosmetics include compositions that may
have, or that are asserted as having, health enhancement
properties, for example, "sun screen" agents in facial creams, to
minimize potentially harmful levels of ultra-violet solar
radiation, and lotions that include anti-oxidants.
[0003] With regard to cosmetics applied to the lips, these are
available in a range of products, colors and textures. Lipstick is
well known, and is most commonly supplied in a cylindrical
container that allows presentation of the "stick" as a colored,
waxy solid that can be easily applied to the lips. Lipstick
generally includes pigments that provide the desired color, a
carrier of a mixture of oils and waxes, and emollients
(moisturizers and skin conditioners). Lip-gloss is a sheer
composition applied to the lips, most commonly as a liquid using an
applicator referred to as a "doe foot applicator," to impart a
glossy sheen. Lip balm may include a composition to prevent drying
out of the lips, and may include a moisturizing conditioner. Lip
balm is often clear (not colored) but may be colored. Lip plumper,
which may be solid, gel/cream or liquid, is formulated with
compositions, such as niacin or retinol, or a harmless skin
irritant (e.g., menthol, camphor, cayenne, cinnamon), that causes
the lips to swell and become fuller ("plumper"). Lip plumpers may
range from translucent to any color desired. Lip plumper may be
formulated to be used by itself as a lip-gloss, or may be
formulated for receiving an application of lipstick over the lip
plumper.
[0004] While there has been a growing trend toward the use of
"natural" ingredients and organic ingredients in cosmetics, there
has also been a demand for cosmetics that are suited to an active
lifestyle, and for a busy work day. As a result, there has been a
growing market for a long wearing lipstick that does not require
frequent application and does not come off the wearer's lips
readily, so that fresh application, or "touch up," might be
required fewer times daily, sometimes only once or twice in an
eight hour work day. In response to this need, the cosmetics
manufacturers developed new lipstick formulations. The
"traditional" lipstick, which generally has to be "freshened"
several times a day, has a "soft waxy solid" carrier structure that
results from the use of a wax, or a mixture of waxes, typically
including carnauba wax (a high melting point wax for structural
support), beeswax, ozokerite, and candelilla wax. The carrier
formulation further includes oils and fats that are blended with
the waxes to provide the texture and sheen of the lipstick. These
oils and waxes include, for example, olive oil, mineral oil, cocoa
butter, lanolin, and petrolatum. Some may contain pig fat and
castor oil in addition, to improve the shiny appearance when
applied.
[0005] The recent introduction of "long wearing" lipstick was made
possible by changes in lipstick formulations to include
compositions that reduce the tendency of traditional lipstick to
gradually wear off the lips during normal daily activities of
talking, drinking, eating, etc. These formulations adhere more
stubbornly to the lips, and may also be expected to adhere more
stubbornly to other surfaces, for example the surface of a drinking
glass or cup. This lipstick residue often resists cleaning in
ordinarily used cleaning methods, for example automatic dish
washing machines used in restaurants, resulting in the embarrassing
presentation of a "cleaned" glass or cup with lipstick residue to a
customer.
[0006] US Patent Publication 2005/0227884 discusses a method of
removing lipstick residue, particularly such residue from long
wearing lipstick, from a glass or cup (collectively, "drink ware")
by pretreating the used drink ware with a chemical formulation
prior to the usual cleaning in a dish washing machine. The
pretreatment formulation includes at least 0.1 to 100 wt. % of a
solvent specified as a ketone; an ester, such as the soy esters; a
paraffin hydrocarbon, such as Norpar 13, available from Exxon
Mobil; and a glycol ether, glycol, or a terpene. In addition, the
formulation includes an organic surfactant (from a specified list),
a hydrotrope to assist in dissolving all the components of the
formulation, a dye a viscosity modifier, and a source of
alkalinity, such as sodium or potassium hydroxide, and a builder,
such as sodium tripolyphosphate. The pretreating formulation is a
liquid solution and may be applied either only to the rim of the
drink ware, where the residue is typically found, or to the entire
drink ware surface. The pretreatment solution can be applied by
spraying, misting, foaming, dipping, wiping, fogging, or rolling.
Thereafter, the drink ware is washed in a washing machine. There is
no indication that the pretreatment solution is non-toxic, or that
it can be ingested in any amounts, without harm. Since the drink
ware is subsequently cleaned in a washing machine, toxicity may not
be of concern.
[0007] U.S. Pat. No. 5,346,640 relates to a cleaning composition,
asserted to clean graffiti from walls, and also lipstick from
surfaces. The patent describes five different cleaning liquid
compositions, each directed to a specific cleaning job. Each of the
cleaning liquids includes the "stem ingredients" which are
N-methylpyrrolidone, propylene carbonate, isocetyly alcohol,
dipropylene glycol methyl (or mono-methyl) ether acetate.
[0008] PCT Publication WO 1998/004660 is directed to a glass
washing composition said to be effective in cleaning lipstick from
glass. The composition includes a nonionic surfactant, a suitable
solvent, such as water, and optionally a co-solvent, such as a
short chain alcohol. The nonionic surfactant may be present in the
range 2.5 to 50 wt. %, and is preferably a low foaming surfactant
selected from the alkoxylate surfactants. The co-solvent is
preferably selected from isopropyl alcohol, white mineral spirits,
glycols and sodium cumene sulfonate.
[0009] U.S. Pat. No. 4,600,522 relates to a biodegradable cleaning
composition asserted to be effective in cleaning lipstick residues.
This cleaning composition includes a furan-based alcohol mixed with
a nonionic surfactant, an aromatizing composition, and an
emulsifier.
[0010] U.S. Pat. Nos. 6,812,202 and 6,436,893 relate to an alkaline
detergent composition asserted to be effective in cleaning lipstick
residues. The detergent composition includes a blend of nonionic
surfactants, an alkyl polyglycoside surfactant, and a silicon
surfactant having a hydrophobic group and a pendant hydrophilic
group.
[0011] A study in Spain showed that the tops of soda cans are more
contaminated and full of germs and bacteria. So to wash them with
water is advised before putting it to the mouth to avoid any kind
of fatal accident. Beverage containers frequently have provision
for opening a portion of the top of the can so that the purchaser
can drink the contents directly from the can. The area that is to
serve as the discharge opening is formed as a "knock-out" in the
metal top, and a ring is secured to the knock-out near the center
portion of the can top for tearing the knock-out from the can top
so as to provide the discharge opening. Such containers have the
disadvantage that the top of the can becomes dirty as the result of
dust settling on it or other contaminants falling on it while it is
standing on store shelves or elsewhere. Additionally, rodents and
other pests can spread waste products onto the surfaces of the
containers. Moreover, insecticides can be sprayed on areas where
the cans are stored, and this insecticide accumulates and dries on
top of the can. People who buy these containers often open them for
immediate consumption and without either the facilities or the
inclination to wash the container before bringing their lips in
contact with the contaminated surfaces. Health authorities in some
jurisdictions require that such self-opening containers have a
plastic cover over the area around the discharge opening for
protection from contamination. Such plastic covering adds
considerable expense to preparation of the containers for sale; and
the equipment for applying such plastic covers is a large expense
to plants where beverage containers are labelled and packed.
Furthermore, such plastic covers are not adequate for preventing
contamination, because customers have favorite flavors and they
break open several packs on the supermarket shelf and collect
different favorite individual flavors which they purchase at the
check-out counter. Store managers cannot effectively prevent this
practice and the unsold containers remain on the store shelf with
some or all of the containers deprived of their protection against
dust, dirt and other contamination. Some of the containers that are
purchased are stored on pantry shelves and elsewhere where they
gather dust and dirt with no protection whatever for the areas
around the discharge opening. Sometimes rats in the storage shelves
may contaminate with urine that contains toxic and deadly
substances.
SUMMARY
[0012] Exemplary embodiments of the technology provide
formulations, applicators or carriers for the formulations, and
methods of using the formulations to remove cosmetic residue from
surfaces, especially for removing more stubborn residues, such as,
for example, long wearing lipstick residue from drink ware,
clothing, and other surfaces. In the case of clear or translucent
surfaces, the formulations provide a cleaned surface that is
streak-free and shiny-clean to the eye.
[0013] In an exemplary embodiment, a non-toxic, sanitizing
formulation for removing contaminated residue from the tops of
beverage cans, coffee mugs and wine glass surfaces includes a
non-ionic surfactant; water soluble preservative; pH reducer,
chelating agent; glycerin; water; and optionally an edible
fragrance. Optionally, the exemplary formulation may include from
about 2.7 to about 3.3 wt. % isopropyl alcohol, or about 3 wt. %.
Further optionally, the surfactant may be present at from about 0.5
to about 1 wt. %, or about 0.75 wt. %. Further optionally, the
surfactant may be Caprylyl or Decyl Glucoside. Optionally, the
formulation may have from about 0.2 to 0.3 wt. %, or about 0.25 wt.
% of water soluble preservative. Further optionally, the water
soluble preservative may be sodium benzoate or potassium sorbate or
a combination thereof. Optionally, the formulation may have from
about 0.1 to about 0.5 wt. %, or about 0.25 wt. % of chelating
agent. Further optionally, the chelating agent is Phytic acid.
Optionally, the formulation may have less than 0.01 wt. % of a pH
reducer. Further optionally, the pH reducer is Citric acid.
Optionally, the formulation may have less than 0.01 wt. % of
glycerin.
[0014] Another exemplary embodiment provides a wipe impregnated
with a non-toxic, sanitizing aqueous formulation for removing long
wearing lipstick residue from glass, porcelain and plastic
surfaces. Yet another exemplary embodiment provides a wipe
impregnated with a non-toxic, sanitizing aqueous formulation for
removing contaminated residue from the tops of beverage cans,
coffee mugs and wine glass surfaces. The wipe acts as a carrier for
a formulation and has about 2.7 to about 3.3 wt. % isopropyl
alcohol, or 0.2 to 0.3 wt. %, or about 0.25 wt. % of water soluble
preservative; an non-ionic surfactant; chelating agent; water
soluble preservative; pH reducer and optionally an edible
fragrance; and water. The wipe may optionally be made of woven
fibers, such as nylon, cotton, and the like. Moreover, the wipe may
be textured to provide a mild soft scrubbing to a surface and/or
may be textured to enhance polishing of surfaces. The wipes can be
individual wipes, individually packaged in a water tight, tearable
enclosure, or can be a roll of connected, but perforated wipes in a
tube for dispensing through.
[0015] In some exemplary embodiments the formulation is an aqueous
liquid, and in other exemplary embodiments, it is an alcohol-based
solution, free of water, which is added in the cleaning stage. In
some embodiments it is supplied in a sealed sachet that dissolves
in water to release the sanitizing and cosmetic residue-cleaning
formulation contained therein. In other exemplary embodiments, it
is provided as a concentrated bulk liquid for dispersal or mixing
into water that will be used to clean cosmetic residue-marked
surfaces and to sanitize these.
[0016] The foregoing summary is not exhaustive; more details and
exemplary embodiments about the cosmetic residue removal
formulation technology that is the subject of the appended claims
are provided here below.

DETAILED DESCRIPTION
[0036] The term "exemplary" as used herein, means "an example of,"
and the examples provided herein are non-limiting of the invention,
which is solely expressed in the patent claims.
[0037] In the specification and claims, the term "cosmetic residue"
means residue that results from cosmetics having contacted a
surface and having adhered to that surface after such contact.
Sometimes at least a portion of that residue remains tightly bound
to the surface, even after a standard cleaning procedure,
appropriate to that surface, has been applied. While much of the
following discussion focuses on lipstick, and long wearing
lipstick, other cosmetics may have similar effects with regard to
residues. Further, while much of the discussion may focus on drink
ware, for ease of explanation, the formulations are also useful in
cleaning other surfaces, such as clothing of natural or synthetic
materials, or both, utensils, plates, pacifiers and anything that
needs a sanitary finish.
[0038] In the specification and claims, the term "contaminated
residue" means residue that results from dust, dirt, insecticides
and/or any other particles including feces and urine that might
collect on a surface and/or adhere to that surface after such
collection.
[0039] The term non-toxic, as used in the specification and claims
means compositions, and formulations of these compositions, that
are either not toxic when ingested or that are present in such
minute and barely detectible residual amounts, if any, on cleaned
surfaces as to pose virtually no risk to human health, if ingested
in food or drink in contact with that surface.
[0040] The term "sanitizing" as used in the specification and
claims relates to the capability of embodiments of the formulation
to clean surfaces having a cosmetic or contaminated residue of
micro-organisms associated with that residue, to thereby
significantly reduce the population of the micro-organism and any
associated risk.
[0041] The introduction of long wearing lipstick has exacerbated an
issue that has long presented in the field of cleaning glass and
porcelain surfaces, in particular, of lipstick residue resulting
from contact with lips of the wearer. Even after washing drink
ware, for example, in a dish washing machine, at temperatures
selected to ensure sterilization of pathogens, the residue often
remains. Although the drink ware is not contaminated with
pathogens, the residue is nonetheless unsightly and evokes feelings
of distaste, resulting in a diminished impression of the standards
of hygiene of an establishment that serves beverages in such drink
ware. The removal of such residues is, therefore, of some
significance to business establishments.
[0042] In addition, sometimes when make-up is being applied, the
lipstick might slip from the grasp and in falling cause a mark on
clothing: a blouse, scarf, skirt, pants, or the like. These marks
are not readily removable with standard cleaning techniques,
especially marks from long wearing lipstick. In fact, some
techniques may result in "setting" of the mark and make it
virtually impossible to remove this cosmetic residue later.
Depending upon the prominence of the cosmetic residue, this
potentially permanent "stain" may result in the clothing item being
perceived as "ruined" and not fit for further use.
[0043] The recently introduced long wearing lipsticks pose more
significant residue issues than the older "traditional lipsticks."
For example, referring to FIG. 1, even after putting drink ware,
exemplified by wine glass 100, through a dish washing machine,
stubborn residue 102 remains on the surface in the rim region 104
of the glass 100. The residue 102 may be more stubbornly attached
in some cases and may be "baked on" after being subjected to high
temperature washing with detergent, and hot air of drying of the
washing machine. The same applies to long wearing lipstick marks on
clothing that are "set" after heat drying during laundering.
Whereas the traditional (not long wearing) lipstick formulations
included waxes and oils, the long wearing lipsticks include
wax-like synthetic polymers (also referred to herein as "polymeric
waxes") and dimethicones. These polymeric waxes and dimethicones
provide the long wear characteristic, but also contribute markedly
to producing the stubborn cosmetic residue.
[0044] An exemplary embodiment provides a sanitizing formulation
for removing cosmetic residue from surfaces, especially glass,
porcelain, and polymeric surfaces and the surfaces of clothing made
from natural or synthetic fibers, or a combination of both. It is
theorized, without being bound, that the efficacy of the exemplary
formulation may arise from its component compositions. These
compositions include a polar solubilizer for the polymeric waxes
and dimethicones present in the long wear lipsticks. The
solubilized polymeric waxes may interact with a surfactant, and are
thereby rendered soluble in either the water of the formulation, if
in aqueous form, or water added in the cleaning process. Because of
detergent activity, the polymer waxes and dimethicones do not
re-deposit. In addition, the formulations may include an
anti-streaking agent that finish-cleans the surface to remove any
streaks visible to the naked eye, and a conditioning agent that
imparts a shiny, clean appearance.
[0045] In an exemplary embodiment, the surfactant is a non-ionic
surfactant, or a mixture of such surfactants. In another exemplary
embodiment, the surfactant is an ionic surfactant, or a mixture of
such surfactants. Of these surfactants, a non-limiting, useful
surfactant, or mixture of surfactants, may be selected from
Caprylyl or Decyl Glucoside. Non-ionic surfactants that are
non-toxic at levels of concentration left on cleaned surfaces, and
with low or no risk of allergic reactions at these concentrations,
are preferred. Furthermore, the surfactants may have some
antimicrobial (preserving) ability. In addition, the surfactants
may be mild, low in toxicity, readily biodegradable and do not
leave any streaks on the surfaces that are cleaned.
[0046] In an exemplary embodiment, the anti-streaking agent that
cleans clear or translucent surfaces to a visibly streak-free
appearance may be isopropyl alcohol, for example, or a like
anti-streaking agent. Anti-streaking agents that are non-toxic at
levels of concentration left on cleaned surfaces, and with low or
no risk of allergic reaction are preferred. A combination of the
isopropyl alcohol along with the surfactants cleans surfaces to a
visibly streak-free appearance while providing anti-microbial
properties.
[0047] The anti-streaking agent is not essential, for example on
porcelain that is opaque, but provides an added assurance of a
streak free shine to clear or translucent surfaces, for example,
acrylic or glass stem ware.
[0048] In an exemplary embodiment, the combination of a water
soluble preservative, a chelating agent, and pH adjuster in the
formulation may prevent the product and/or the formulation from
microbial contamination. Isopropyl alcohol content by itself may
not be sufficient enough to preserve the product. A chelating agent
may sequester metals from the water or the aqueous formulation. In
an exemplary embodiment, a non-limiting example the chelating agent
may be phytic acid. According to another exemplary embodiment, the
sanitizing formulation may further comprise a pH reducer such that
the preservatives in the formulations are more effective. In an
exemplary embodiment, a non-limiting example pH reducer may be
citric acid.
[0049] In an exemplary embodiment, a non-limiting example of the
conditioning agent may be glycerin. Glycerin is non-toxic and
provides a shiny, cleanly polished look to smooth surfaces, such as
glass, acrylic or porcelain, for example. Conditioning agents that
are non-toxic at levels of concentration left on cleaned surfaces,
and with low or no risk of allergic reactions at these
concentrations, are preferred.
[0050] In an exemplary embodiment, a non-toxic, sanitizing
formulation for removing contaminated residue from the tops of
beverage cans, coffee mugs and wine glass surfaces includes a
surfactant; water soluble preservative; pH reducer, chelating
agent; glycerin; water; and optionally an edible fragrance.
Optionally, the exemplary formulation may include from about 2.7 to
about 3.3 wt. % isopropyl alcohol, or about 3 wt. %. Further
optionally, the surfactant may be present at from about 0.5 to
about 1 wt. %, or about 0.75 wt. %. Further optionally, the
surfactant may be Caprylyl or Decyl Glucoside. Optionally, the
formulation may have from about 0.2 to 0.3 wt. %, or about 0.25 wt.
% of water soluble preservative. Further optionally, the water
soluble preservative may be sodium benzoate or potassium sorbate or
a combination thereof. Optionally, the formulation may have from
about 0.1 to about 0.5 wt. %, or about 0.25 wt. % of chelating
agent. Further optionally, the chelating agent is Phytic acid.
Optionally, the formulation may have less than 0.01 wt. % of a pH
reducer. Further optionally, the pH reducer is Citric acid.
Optionally, the formulation may have less than 0.01 wt. % of
glycerin. The remainder of the composition is water, preferably
deionized, to avoid ionic interference with the surfactant
activity.
[0051] FIG. 2A depicts an exemplary embodiment of a wipe dispenser
200, including a container 202 with a roll of wipes 204 therein.
The wipes 206 may be pulled through the top 208 of container 202,
which has means to detach one wipe 206 at a time as it exits from
the container 202. An exemplary embodiment of a wipe 300, depicted
in FIG. 3 has a first side 302 that includes texture 304 providing
a roughened surface for scrubbing. The texture may be created by
fibers, or by other suitable inclusions within the wipe material.
The other side 302 of the wipe is not visible, but may be roughened
or may be free of such surface roughening features, and may be
suitable for polishing.
[0052] FIG. 2B shows an alternative embodiment in which a plurality
of wipes 226 are enclosed within a hinged case 210 that is sized to
facilitate carrying in a women's purse or bag. In a non-limiting
example, the case 210 may be about 2.5 inches wide, by about 4.5
inches long, and about 0.5 inches thick, and may have an attractive
design (or coloration) on at least the upper surface 218 of lid
212. The lid 212 of case 210 is hinged to the base 214 that has an
internal cavity for receiving multiple suitable folded wipes 226.
The upper surface of the base 220 includes a slot 216 through which
individual wipes 225 may be pulled from the case, one after the
other. To facilitate refilling the case 210 when all wipes have
been removed and used, the base 214 may have a hinged or otherwise
removable upper lid 220 that allows access to the cavity inside
base 214 for placing replacement wipes 226 therein. In an exemplary
embodiment the case may be made from a suitable light-weight
plastic material that is substantially non-reactive with the
formulation on the wipes. In order to minimize evaporation of
formulation from the wipes 226, the lid 212 may be designed to fit
snugly over the upper edge of base 214 and seals to the base along
the contact perimeter with the base 214. Other containment
techniques to minimize evaporation may also be used.
[0053] FIG. 2C depicts a handy, easy-to-carry sealed-pouch
embodiment 230 of the technology. The pouch 232 contains a single
wipe, or a pair of wipes 236 impregnated with an embodiment of a
non-toxic, sanitizing formulation that is sealed within a pouch 232
of a material that minimizes or prevents evaporation of the
formulation from the wipe(s). Such a material may be selected from
non-reactive plastic films, metalized plastic films, or metal
films. The pouch 232 optionally has a score-line that provides a
line of weakness to facilitate tearing the pouch open to access the
wipe(s) inside.
[0054] Another exemplary embodiment provides a sachet filled with a
non-toxic formulation for removing long wearing lipstick residue
from glass, porcelain and plastic surfaces. In an exemplary
embodiment, the sachet is sealed, but is water soluble, in
exemplary embodiments. The sachet maintains the formulation within
it until the shell of the sachet dissolves in the water that is
used to clean the affected surfaces. As depicted in FIG. 4, the
sachet 400 may be deposited into a clothes washing machine 410, or
a dish washing machine 420, or to a tub 430 for manual washing of
clothes or drink ware, or any other washable articles that have a
cosmetic residue. The formulation a non-ionic surfactant; water
soluble preservative; pH reducer, chelating agent; glycerin; water;
and optionally an edible fragrance. Optionally, the exemplary
formulation may include from about 2.7 to about 3.3 wt. % isopropyl
alcohol, or about 3 wt. %. Further optionally, the surfactant may
be present at from about 0.5 to about 1 wt. %, or about 0.75 wt. %.
Further optionally, the surfactant may be Caprylyl or Decyl
Glucoside. Optionally, the formulation may have from about 0.2 to
0.3 wt. %, or about 0.25 wt. % of water soluble preservative.
Further optionally, the water soluble preservative may be sodium
benzoate or potassium sorbate or a combination thereof. Optionally,
the formulation may have from about 0.1 to about 0.5 wt. %, or
about 0.25 wt. % of chelating agent. Further optionally, the
chelating agent is Phytic acid. Optionally, the formulation may
have less than 0.01 wt. % of a pH reducer. Further optionally, the
pH reducer is citric acid.
[0055] Another exemplary embodiment provides a bulk liquid
non-toxic formulation for removing long wearing lipstick residue
from glass, porcelain and plastic surfaces. The formulation is in
concentrated form and can be diluted with water, preferably
deionized water, in a 50:50 ratio. The bulk formulation prior to
dilution may include from about 2.7 to about 3.3 wt. % isopropyl
alcohol, or about 3 wt. %. Further optionally, the surfactant may
be present at from about 0.5 to about 1 wt. %, or about 0.75 wt. %.
Further optionally, the surfactant may be Caprylyl or Decyl
Glucoside. Optionally, the formulation may have from about 0.2 to
0.3 wt. %, or about 0.25 wt. % of water soluble preservative.
Further optionally, the water soluble preservative may be sodium
benzoate or potassium sorbate or a combination thereof. Optionally,
the formulation may have from about 0.1 to about 0.5 wt. %, or
about 0.25 wt. % of chelating agent. Further optionally, the
chelating agent is Phytic acid. Optionally, the formulation may
have less than 0.01 wt. % of a pH reducer. Further optionally, the
pH reducer is citric acid.
[0056] Referring to FIG. 5, the bulk liquid may be dispensed in
measured amounts into an exemplary embodiment of a drink ware
washing apparatus 500. The apparatus 500 includes a substantially
cylindrically shaped tub 510 that is at least partially filled with
a formulation according to an exemplary embodiment. The tub 510 has
a central vertical guide 520 adapted to receive the opening of a
glass 530 or cup. By guiding the rotation of the glass 530
appropriately, its rim 535 that has cosmetic residue rubs against
the inner side surface 545 of the tub 510 as well as against the
outer surface 525 of the guide 520. These surfaces 545 and 525 may
be slightly roughened but yielding to facilitate scrubbing of the
cosmetic residue 535 from the glass 530 with the formulation 550
that at least partially fills tub 510. Or tub 510 may be lined with
wipes, as described above, to facilitate the rapid cleaning of
large numbers of glasses in a short time.
[0057] An exemplary embodiment of the formulation for removing
cosmetic residues from surfaces includes chemical components that
are non-toxic and have low risk of producing an allergic reaction
when a human is exposed to the minor amounts left behind on a
surface after that surface has been cleaned using the formulation,
whether such exposure is by touch or through ingestion as from
cleaned drink ware.
[0058] FIG. 6, depicts cosmetic residue 604 on a textile fabric, in
this example, a collar 602 of a shirt or blouse 600. An exemplary
embodiment of the non-toxic formulation of the technology may be
supplied in a spray bottle 610. This permits spraying a directed
spray or stream of the formulation directly onto the contaminated
area of the clothing to facilitate removal of the cosmetic residue
604. This removal may require additional actions, such as blotting
with an absorbent cloth or sponge and repeated application of the
spray-on formulation. Alternatively, a wipe 620, like that
described above, with reference to FIG. 3, for example, impregnated
with an embodiment of a formulation in accordance with the
invention, may be used to selectively blot formulation onto the
area affected by the cosmetic residue 604 and to thereby remove it.
During blotting, care should be taken to avoid spreading the
cosmetic residue to other parts of the garment or fabric.
[0059] FIG. 7A, depicts a beverage can 700 with contaminated
residue 701 collected on the can. Such beverage cans have the
disadvantage that the top 702 of the can becomes dirty as the
result of dust settling on it or other contaminants including feces
and urine falling on it while it is standing on store shelves or
elsewhere. Sometimes insecticides are sprayed on areas where the
cans are stored, and this insecticide accumulates and dries on top
of the can. People who buy these beverage cans often open them for
immediate consumption and without either the facilities or the
inclination to wash the beverage cans before bringing their lips in
contact with the contaminated surfaces. An exemplary wipe
impregnated with a formulation to clean the contaminated residue
from the beverage can may comprise the following composition as
illustrated in Table 1.0.
TABLE-US-00001 TABLE 1.0 INGREDIENTS % w/w Water 93.00-98.00
Isopropyl Alcohol 2.70-3.30 Caprylyl/Decyl Glucoside 0.50-1.00
Sodium Benzoate 0.20-0.30 Phytic Acid 0.10-0.50 Potassium Sorbate
0.10-0.30 Glycerin <0.01 Citric Acid <0.01
[0060] Another exemplary wipe impregnated with a formulation to
clean the contaminated residue from the beverage can may comprise
the following composition as illustrated in Table 2.0.
TABLE-US-00002 TABLE 2.0 INGREDIENTS % w/w Water 75.00-98.6988

[0061] A further exemplary embodiment provides a sanitizing wipe
impregnated with a non-toxic aqueous formulation for removing
cosmetic residue such as long wearing lipstick residue from glass,
porcelain and plastic surfaces. Yet another exemplary embodiment
provides a sanitizing wipe impregnated with a non-toxic aqueous
formulation for removing residue contaminated with dirt and dust
from surfaces such as beverage cans, coffee mugs and the like. The
wipe acts as a carrier for a formulation having a non-ionic
surfactant; water soluble preservative; pH reducer, chelating
agent; glycerin; water; and optionally an edible fragrance; and
water. The wipe may optionally be made of woven fibers, such as
nylon, cotton, paper-pulp fiber, and the like, and mixtures of such
fibers. Moreover, the wipe may be textured to provide a mild soft
scrubbing to a surface and/or may be textured to enhance polishing
of surfaces. An exemplary embodiment includes a wipe that has a
rougher texture on one side for facilitating a slight scrubbing
action, and a smoother surface of the other side to facilitate a
polishing action. Optionally, the exemplary formulation may include
from about 2.7 to about 3.3 wt. % isopropyl alcohol, or about 3 wt.
%. Further optionally, the surfactant may be present at from about
0.5 to about 1 wt. %, or about 0.75 wt. %. Further optionally, the
surfactant may be Caprylyl or Decyl Glucoside. Optionally, the
formulation may have from about 0.2 to 0.3 wt. %, or about 0.25 wt.
% of water soluble preservative. Further optionally, the water
soluble preservative may be sodium benzoate or potassium sorbate or
a combination thereof. Optionally, the formulation may have from
about 0.1 to about 0.5 wt. %, or about 0.25 wt. % of chelating
agent. Further optionally, the chelating agent is Phytic acid.
Optionally, the formulation may have less than 0.01 wt. % of a pH
reducer. Further optionally, the pH reducer is Citric acid.
Optionally, the formulation may have less than 0.01 wt. % of
glycerin. The beverage can in one preferred exemplary embodiment
may be packaged with the exemplary sanitary wipe impregnated with
the formulation to enable a user to wipe the top surface of a
beverage can providing a sterile surface free of micro-organisms
associated with the residue on the contaminated surface. The user
may open the can for immediate consumption before bringing their
lips in contact with the top of the beverage can. The wipe may
further be packaged with the beverage at a plurality of points
through any adhesion means. For example, as illustrated in FIG. 7B,
the wipe 704 could be packaged to the sides 708 of the can. In
another example illustrated in FIG. 7C, the wipe may be attached to
the bottom 706 of the beverage can 700 in the concealed portion
which may be concave shaped. It must be noted that the wipe may be
packaged at any attachment point of the beverage can and the
locations of the attachment points may not be construed as a
limitation. Additionally, according to another exemplary
embodiment, the wipe may be disconnected and used separately to
clean the surfaces of a beverage can providing a sterile surface
free of micro-organisms associated with the residue on the
contaminated surface. Similarly, as illustrated in FIG. 8, the
exemplary wipe 803 cleans residue 801 collected on a wine glass
800. The sanitizing wipe may be impregnated with a non-toxic
aqueous formulation for removing residue contamination on surfaces
of wine glasses and beverage cans. The wipe acts as a carrier for a
formulation having a non-ionic surfactant; water soluble
preservative; pH reducer, chelating agent; glycerin; water; and
optionally an edible fragrance; and water. Likewise, as illustrated
in FIG. 9, the exemplary wipe 903 cleans residue 901 collected on a
coffee mug 900. The sanitizing wipe may impregnated with a
non-toxic aqueous formulation for removing residue contaminated
with dirt and dust from surfaces of the wine glass. The wipe acts
as a carrier for a formulation having a non-ionic surfactant; water
soluble preservative; pH reducer, chelating agent; glycerin; water;
and optionally an edible fragrance; and water. The sanitizing wipe
may be used on several surfaces such as a deli table for making
sandwiches and that needs a sterile surface. Another application is
spouts of a bottles such as sport bottles that are consumed
directly from the spout.
[0062] FIG. 10A depicts an exemplary embodiment of a single sheet
wipe 1000 of FIG. 2 comprising a scrubbable portion 1001 and a
clean portion 1002. The scrubbable portion may be impregnated with
the exemplary formulation. A user may hold the clean portion 1002
while scrubbing or cleaning a residue on a surface with the
scrubbale portion 1001 so that the user does not contact the
formulation. The wipe 1000 may be divided into equal or unequal
portions of the scubbable and clean portions. For example, the
scrubbable portion 1001 may be 50% and the clean portion 1002 may
be 50% of the area of the wipe. In another example, the scrubbable
portion 1001 may be 70% and the clean portion 1002 may be 30%. The
formulation in the wipe may be ingestible unlike commercially
available sanitizing wipes.
[0063] FIG. 10B depicts an exemplary embodiment of a single sheet
wipe (1010) of FIG. 2 with a single texture (1011). The texture may
be customized to be smooth, rough or mild depending on the extent
of sanitization or the extent of surface that needs to be
sanitized.
[0064] FIG. 10C depicts an exemplary embodiment of a single sheet
wipe (1020) of FIG. 2 comprising a first texture (1021) on a first
side and a second texture (1022) on a second side. The first side
and second side may be selected to be the two faces of the wipe.
Alternatively, the first side and the second side may the
diagonally separated.
[0065] FIG. 11A depicts a mobile device (1100) with contaminated
residue (1101) collected on the device. The devices may be carried
along in a purse, pocket, car holder and the like and are therefore
prone to contamination. The device may collect contamination when
they are carried to places such as restrooms, crowded fields,
restaurants, kitchens, malls, and so on. An exemplary wipe (1107)
impregnated with a formulation to clean the contaminated residue
from the mobile device may comprise the composition as illustrated
in Table 1.0 or Table 2.0. FIG. 11B depicts an exemplary wipe
attached to the back of a mobile device (1100) so that the device
may be cleaned as necessary.
[0066] While exemplary embodiments have been particularly shown and
described, it will be understood by those skilled in the art that
various changes in form and detail may be made therein without
departing from the spirit and scope of the patent claims, and such
equivalents thereof that a court may provide under the doctrine of
equivalents.
